Implemented hostility system - entities can mark each other as friend or foe depending on changing conditions (currently only depends on local security level)
Added "friendly" target indicators in blue
Added ping feature to sensors, pulsing a wave of revealing light into the level
Added IEventBehavior interface, used by sensors and weapons, for behaviors containing event subscriptions which need to be reset when EntityInstance is disposed
Implemented sensor impact for locked weapons (lock speed varies with sensor acquisition)
Added ping cooldown bar to HUD
Added spline curve implementations to AetheriaMath, applied better mapping to wormhole transition animation
Tweaked loadout generator to prefer larger items to a controllable degree (e.g. very important for cargo bays, less for shop inventory), shop inventory bans non-ship hulls and manages internal space more effectively
